I am getting a parsing error and I do not know why (I am new to programing). Because of this error, R.java disappears and I end up having more errors. Hopefully someone can help me out. Here is where the error comes from: list.xml. Code...

I have a weird issue. I receive the following error that causes a force-close:
CODE:...........
After clicking the Force Close button, the Activity is recreated and the parsing completes without a hitch. I'm using the following code snippet inside doInBackground of an AsyncTask:
CODE:.......................
Why would the Activity force-close and then run without any problems immediately after? Would a BufferedInputStream be any different? I'm baffled.
It turns out HttpURLConnection.getResponseCode() returns -1 every so often, so the InputStream probably isn't being correctly set.
I added some UI elements to the main.xml file in the reslayout folder and when I try to access them through the call, R . layout. my _ uielement, the UI element that I created is not there. Even when I add a new xml file with UI elements, it still doesn't show up in the R.layout class. I have made checked the ids on them and they have the correct format (I think): android:id="@+id/my_button". What could be the problem? Do I need to compile the code first? UPDATE: I have already tried adb kill-server then adb start-server. It doesn't seem to help. I have also tried R.id.my_uielement, it doesn't register either.
View 2 Replies View RelatedIs there a way to lookup the line number that a given element is at in an xml file via the w3c dom api?
My use case for this is that we have 30,000+ maps in kml/xml format. I wrote a unit test that iterates over each file found on the hard drive (about 17GB worth) and tests that it is parseable by our application. When it fails I throw an exception that contains the element instance that was considered "invalid". In order for our mapping department (nobody here knows how to program) to easily track down the typo we would like to log the line number of the element that caused the exception.
Can anybody suggest a way to do this? Please note we are using the W3C dom api included in the Android 1.6 SDK.
Does someone know how to generate a javadoc for an android project? I found searching the net this info http://www.androidjavadoc.com/?p=63 , but i don't understand where can i find the file "droiddoc.mk": "All javadoc stuff is concentrated in the ROOT/build/core/droiddoc.mk".
View 3 Replies View RelatedI have an Java class with a static final method getAll:
CODE:..............
Now I want to hand in null as a value for the where statemant so that it will just be ignored later on in the code. Anyway in the testcase for this method I have: Vector<Category> categories = Category.getAll(context, null);
Which then in turn gives me a NoSuchMethodError. I don't know exactly why it does that. The only thing I could imagine is that the null I hand in would not match the signature of the above method. But how can I overcome this? I already thought of overloading. But this would just end in rewriting most of the code. At least when I do it, how I think.

Does anyone know what approach one can take to automatically generate Java source code, from for example an xml or json file, in eclipse? One great example of what I am thinking of doing is what Google Android sdk does: they have an R class generated automatically from the resources. Every time a resource file is saved in Eclipse R class is automatically regenerated.
UPDATE: Example:
In the text (xml or json file) I have the following:
<tags>
<tag id="ALPHA">
<description>The first alpha tag.</description>
<value>231232</value> </tag> <tag id="BETA">
<description>This is the beta tag.</description>
<value>231232</value> </tag>
Then in my generated java class, say R I would have something like:
R.tags.ids.ALPHA //refers to an enum value for example
R.tags.values.ALPHA //refers to final int with avlue 231232
R.tags.descriptions.ALPHA //refers to the String with description
I am trying to run android sample applications using intellij idea and R.java file is missing form notepad samples source directory.

I am developing android application on Linux platform because i have to make a system.img with a application.
When adding a drawable resource and building the project with mm command, i met a below error.code..
At above error, the icon_send_type is the added resource.
This error occurred because the mm command did not generate R.java.
So, i want to know how to generate R.java by a manual on Linux platform.
Is there a way to achieve the following in Android?
1. generate a Java stack trace in Android. In J2SE, we use to use something like this - send a signal to the Java Virtual Machine; the Java Virtual Machine generates a stack trace for you; or we can also use debugging tools or Java API calls.

Today I've bought new laptop, windows 7. on my old windows xp android sdk was working 100%.
Every time i start the setup i get this error: [see attachment]
I have downloaded and installed every necessary component in order to start working with Android. The issue I am having is that in Command Prompt, anything I type in related to the Android SDK (for example: adb, or even just android) comes back with "Java was not found in your path". Now, I have changed all my PATH variables under "User" to the EXACT locations of where these folders are, but no dice. It keeps telling me to go and edit my PATH variables. Even running SDK Setup, gives me the same error, and tells me to add where Java was found (even though I have!).
I am starting to get really fed up with this, because Eclipse can't find the "jre" folder inside the Java JDK, either (that is, of course, until I copy the entire jre folder inside of the eclipse folder, or put eclipse inside of the JDK folder)...
I just know it shouldn't have to be this tedious to set everything up.
I am running Java JDK 1.6.0_21 (x64), Eclipse Helios (3.6) IDE for Java EE Dev., Android SDK Revision 6, all on Windows 7 Ultimate x64.
Something to note: I have not encountered any problems with Eclipse Helios and the ADT plugin as stated on the Android Developers website. I can use Eclipse and the SDK to create and run the"Hello, Android!" application on the emulators without issues. I just want to be able to run everything from the command prompt, too. Now, if I can only get my phone to be recognized after I get this resolved.
I am using official android facebook SDK (downloaded from here: http://github.com/facebook/facebook-android-sdk). When the program reaches the line Facebook facebook = new Facebook(); i get "java.lang.NoClassDefFoundError: com.facebook.android.Facebook".

The project builds ok, I have no errors.

I'm using hierarchyviewer to look through a widget that I'm using. (TimePicker).

I would like to know whether there is a way to insert/inject a <string> element defined in an XML file into another <string> element, doing that just with XML.
For example I could have:
<string name="author">Francesco</string>`
and I am looking for something like:
<string name="about_application">Author: @string/author</string>`
so that getString(R.string.about_application) would result in "Author: Francesco".
I know that I could combine the two elements in Java code using String.format(string, formatArgs)like for example:
<string name="author">Francesco</string>
<string name="about_application">Author: %1$s</string>`
and then in code use
String.format(getString(R.string.about_application), getString(R.string.author))
but I would like to do it in XML directly. Can anyone suggest me a way to do it?

In the application I am working on now I came up with the following problem. I have list view which is displaying items with images in most cases it will be different image for different items (thumbnails about 60x60 pixels). So the problem is how can I handle image processing for the view. For know I have the following variants:
1. I can cache all bitmaps and when I try to display view I get bitmap from cache synchronously and display it. The problem is that 60x60=3600x4=14kb per bitmap which is waste of resources.
2. When I need to display view I can register event to some thread to decode the associated bitmap which will decode it in background and than to update gui. This sounds good for me the scrolling is still smooth because all image processing is done in background. Updating list view is bit jerky for now I am doing it view notifyDataSetChanged which is updating all visible views although I can update thumbnail for a single item.
So question one is is there better way the update single listview element than calling notifyDataSetChanged.

View 4 Replies View RelatedI'm loading a URL into a WebView and I'm having difficulty setting the "scale" of the web-page. Specifically, the web-page is too big (800x600) for the screen, so my thought is to use "setInitialScale(50)" to reduce the size. Here is some sample code that doesn't work (i.e. the web-page doesn't scale to 50%)
WebView wv = (WebView)findViewById(R.id.webview);
wv.loadUrl("http://www.example.com/android/symptom");
wv.setInitialScale(50);
I also tried switching the order of the function calls but I get the same result¦i.e.,
WebView wv = (WebView)findViewById(R.id.webview); wv.setInitialScale(50); wv.loadUrl("http://www.example.com/android/symptom");
As an alternative, I have tried to use the "zoomOut()" function like this:
WebView wv = (WebView)findViewById(R.id.webview);
wv.loadUrl("http://www.example.com/android/symptom"); wv.zoomOut();
This approach works for a split second, and then the image reverts to its original size.

Can someone please tell me how to change tab by clicking on element INSIDE the tab? I already tried it with global data.
Now when I'm trying to change tab in my ListActivity tab by clicking on one of the items it doesn't do anything and stays on the ListActivity tab. Perhaps I shouldn't use onResume() here. Basically I want to go to first tab when I click on one of the items in the list. Please help!
